Get usual right side toolbar in UV Editing mode
First to clarify the names used for each part of the window layout which is explained in the introduction page of blender's manual, each window contains one or more areas.

All of the areas combined are saved as a screen layout. Several default layouts are included with blender and you can create as many layouts as you want and easily switch between each one to make various tasks easier.



Each area in a screen layout contains an editor such as the 3DView, Properties Editor, UV/Image Editor, Graph Editor, Outliner ... This leads to editor being a better term to use than area for most users, area is a term used when using python so may be used if you are asking certain python questions.



Each editor has a header (which is often attached to the bottom of the editor) which contains the menus and several widgets specific to the editor, the menu on the left is used to change the editor type. Many editors also have one or two regions available that are attached to the left or right side, these are attached to the side of the editor not the entire blender window. The region on the left is normally the Toolshelf Region (T or &#9096; CtrlT in the text editor) and the one on the right is normally the Properties Region (N). With the mouse over either region or header, you can press F5 to flip it to the opposite side. You will also find a small + on the edge of the editor's area that can be used to view each of these regions when they are hidden.

The toolbar and properties regions, as well as the properties editor, then contains one or more panels that have a disclosure triangle to show/hide the contents. The toolbar region also has tabs to further group the panels.

The part you are thinking of as a properties toolbar is most likely the properties editor (4 above) and can be added to any layout by splitting an area and changing one area to properties, you may also want to split that new area and change one to be the outliner (3 above).

Instead of altering your layout you can also switch to a layout that has the properties and outliner. You can use &#9096; Ctrl&#8592; Left arrow/&#8594; Right arrow to cycle through the screen layouts.

If you adjust your screen layouts and then save your startup file you can have the screen layouts available in each file you create. Note that enabling the Load UI option when opening a blend file will use layouts in the blend file your opening not your startup file.
